Identify each statement as true or false. if a student needs to heat things over 100 °c, then a heating mantle should be used. magnetic stirrers provide sufficient agitation to prevent bumping. never drop a magnetic stir bar into a flask. instead, tip the flask sideways and slide the stir bar in. heating mantles should be plugged directly into an alternating current outlet. for maximum agitation potential, use stir bars and boiling chips together

Liquid ammonia is produced at high temperatures and under great pressure in a tank by passing a mixture of nitrogen gas and hydrogen gas over an iron catalyst. the reaction is represented by the following equation. n2(g) + 3h2(g) → 2nh3(g) changing all but one experimental condition will affect the amount of ammonia produced. that condition is a) increasing the concentration of both reactants b) changing the temperature within the tank c) decreasing the pressure within the tank. d) increasing only the amount of nitrogen present.
